Parts of the PDL embedded in cementum on tooth side and alveolar bone on the opposite side in the wall of the socket
26
Styloglossus
Runs from the styloid process down and foward into the lateral borders of the tongue and blends with the hyoglossus. it pulls the tongue backward and slightly up
27
Cribriform or alveolar bone
Radiographically referred to as lamina dura the tooth socket is constantly being remodeled and additional bone, called bundle bone, laid down on the cribriform plane
28
Apical Group
Runs from the apex of the tooth into the adjacent alveolar bone. this resists forces trying to pull the tooth from its socket
29
Serous Acini
Serous secretion is a thinner, more watery substance
30
Spatial movement of the pre eruptive stage?
The crown develops while the bottom of the socket fills in with bone, pushing the crown toward the surface
31
What kind of muscle is the tongue generally referred to as?
Skeletal or voluntary striated
32
Vertical group
Runs from top to bottom (dorsal to ventral)
33
Specialized Mucosa
Mucosa on the upper surface or dorsum of the tongue
34
Mucocele
Blisterlike lesion that is from Trauma to a minor salivary gland
35
What is root elongation?
Increase in root length, or root elongation, forces the tooth into the oral cavity
36
When is cementum first seen?
at the cervical line of the tooth, also known as the CEJ
37
Circumvallate or vallate papillae
V shaped row of circular raised papillae. There are about 13 elevations located about two thirds of the way back on the tongue with the point of the V facing backward Ex- Taste buds, salty, sweet, sour, bitter
38
tooth eruption is -
multifactorial
39
Col
Part of the interdental papilla that is apical to the contact area that connects the facial and lingual interdental papilla this is a very shallow groove or sulcus around the tooth
40
Post eruptive stage
Begins when the teeth come into occlusion and continues until they are lost or death occurs
41
If you contract the group that runs transverse, what happens to the tongue?
it may get a little thicker and longer
42
Amylase
Carbohydrate splitting enzyme that begins to break down starches into long chain sugars
43
Intrinsic
start and end wholly within the tongue. ``` 4 groups: Superior longitudinal Inferior Longitudinal Transverse Vertical ```
44
free gingival groove
the extent of the free gingiva is usually readily seen because there may be a shallow groove on the gingival surface that corresponds to its depth
45
Transseptal Fibers
Run from the cementum to the interproximal portion of one tooth, across the alveolar crest of bone to the cementum of the interproximal portion of the adjacent tooth this hold the teeth in interproximal contact
46
What arches does the tongue develop from?
The anterior two thirds of the tongue develop from two lateral lingual dwellings and a midline tuberculin impar from the first arch. Posterior one third of the tongue develops from the copula and the third arch The root of the tongue and epiglottis develop from the epiglottal swelling of the fourth arch
47
Mucous Acini
Mucous Secretion is slightly viscous because of the production of several mucins
48
Seromucous Acini
Produce both mucous and serous secretions
49
What are the 2 regions the gingiva is divided into?
Free (marginal) attached These two regions combine to form the peak of gingiva that is the interdental papilla
50
Inferior Longitudinal Group
Runs anterior to posterior but lies near the bottom or ventrum of the tongue
51
Ankylosis
a condition which the alveolar crest of the bone fuses in the cervical area with cementum of a resorbing root
52
What is the color of healthy gingiva?
Pink | but in a diseased state it might become reddish, white or have ulcerations or outgrowths of the mucosa
53
Excentric or off center growth
the crown of a tooth does not grow in a perfectly symmetrical pattern. The center of the tooth is shifting
54
Lining mucosa is made up of :
``` Alveolar mucosa buccal mucosa libial mucosa col gingival sulcus mucosa of soft palate sublingual gingiva and clventral surface of tongue ```
55
Transverse group
Runs from Side to side
56
interaddicular group
found only on multi rooted teeth. this runs from the alveolar crest of the. one between the roots of the tooth to adjacent cementum. resists the forces trying to remove the tooth
57
If you contract the vertical group, the tongue may...
get wider and longer
58
what is the role of the tooth itself?
it plays little if any role in eruption. because of developing teeth have been surgically removed and replaced by metal or silicone implants into the dental sac and these implants have erupted
59
Buccal Mucosa
The mucosa of the cheek is constantly traumatized by chewing. it will become thickened and keratinized in a line corresponding to the occlusal surfaces of the teeth (linea alba)
60
What happens in the pre eruptive stage?
This begins as the crown starts to develop | Eruptive movement associated with this varies as spatial or excentric
61
Interdental papilla
Two regions combine to form the peak of the gingiva that extends coronally between the teeth It's function is to prevent food from impacting interproximally beneath the contact area of the teeth
62
What are the 4 theories of the causes of tooth eruption?
Root elongation Alveolar bone formation and changes vascular pressure in dental tissues the role of the tooth itself
63
Libial Mucosa
Trauma to mucosa of the lip may cause some thickening as in the cheek, but more frequently will cause trauma to minor salivary gland and cause a blisterlike lesion known as mucocele
64
Eruptive stage or pre-functional eruptive stage
Begins with the development of the root the tooth breaks through the mucosal layer and emerges into oral cavity this stage continues until erupting of teeth meet opposing teeth tends to be occlusal, and facial more in anterior than posteriors
65
Spongy or cancellous bone
Between the cortical plate and the cribriform this is a bone marrow a radiograph will only show the cribriform plate, the spongy bone and the crest of the bone that joins two sockets is called the interproximal alveolar crest of bone
66
genioglossus
originates from the genial tubercles on the midline of the mandible and inserts into the midline of the tongue from the tip to the base. it aids in protrusion or depression of the tongue
67
Where does Secretory control come from?
Autonomic nervous system, particularly the parasympathetic nervous system and is tied to chewing, taste and smell
68
palatoglossus
runs from the anterior soft palate down and slightly foward into the lateral borders of the tongue. it elevates the posterior part of the tongue and pulls it slightly backward
69
What is cementum?
Cementum is a hard, yellowish substance covering the root of the tooth. 45-50% inorganic hydroxyapatite 50-55% organic components and water
70
Acini
Secretory end pieces | 2 types- mucous and serous
71
Hairy tongue
Sometimes between the epithelial on the filiform papillae, it grows very long and traps between food and pigments originating oral bacateria and food.
72
xerostomia
"dry mouth" if there is not enough body fluids, saliva production will be decreased and the mouth will become dry and a stimulus to drink more water.
73
what are the several ways the post eruptive stage functions?
1. the mandible continues to grow and increase the space between the maxilla and mandible and the teeth continue to result to maintain balance in the arches 2. the teeth wear oclusally because of prolonged masticatory stress and wear, they will continue to erupt to maintain tooth contact 3. there is slight interproximal wear, there will be a sligh mesial eruptive force that keeps the teeth in contact 4. if an opposing tooth is lost, the tooth may continue to erupt which is called supraeruption and can cause serious problems
74
Papillae
``` the tongue is covered with stratified squamous epithelium 4 types are- circumvallate or vallate papilla fungiform papillae filiform papillae foliate papilla ```
75
Extrinsic muscles
Four pairs of muscles - left and right 1. Hyoglossus 2. Styloglossus 3. Palatoglossus 4. genioglossus
76
Acellular cementum
All of the cementoblasts remain on surface rather than becoming trapped within the cementum
77
When does root formation begin?
it begins after the outline of the crown has been established but before the full crown is calcified. The layers of OEE and IEE make up the epithelial root sheath and begin to undergo rapid mitotic division and grow deep into the underlying connective tissue
78
Lining mucosa
All other areas of mucosa nonkeratinized to parakeratnized and is moveable includes the mucosa of cheeks, lips and soft palate, floor of the mouth beneath the tongue, undersurface or ventral surface of the tongue and alveolar mucosa
79
Filiform Papillae
Remainder of the anterior two thirds of the tongue. It is covered with tiny pointed projections of parakaratinized to kerratinized epithelium. Forms hairy tongue Epithelia of these papillae are lost and surface in that area becomes very smooth- referred to as glottis
80
Alveolar Crest Group
Runs from the cementum, slightly apocal to the alveolar crest of bone. This helps resist horizontal movements of the teeth
81
hypercementosis
the cellular cementum at the apex of the root tends to increase in thickness with the passage of time and as a result causing stress thickening this might make extraction more difficult
82
What are the two groups of the tongue muscle?
Intrinsic and Extrinsic
83
attached gingiva
tightly attached to the underlying connective tissue and bone
84
What fibers are found on multirooted teeth?
Alveolodental Fibers: Interradicular group
85

Cortical plate Cribriform playe or alveolar bone proper spongy or cancellous bone
86
What are the PDL fiber groups?
Gingival Transseptal Alveolodental
87
Sublingual gingiva and central surface of tongue
Epithelium is very thin
88
Average depth of a healthy sulcus
When measured with probe- 2 mm - 3mm
89
Fungiform Papillae
Anterior two thirds of the tongue. have tiny round, raised spots
90
oblique group
Runs from the cementum coronally into the alveolar bone. the main fiber group for resisting occlusal stresses
91
The lining of the oral cavity is referred to as oral mucosa:
it is a stratified squamous epithelial arrangement that runs from the margins of the lips posteriorly to the area of the tonsils
92
what is vascular pressure in dental tissues?
Vascular pressures present enhance cellular activity but seem to have a direct eruptive role
